Description
DURAN® flat-bottom flask with narrow neck and beaded rim is a versatile laboratory vessel of 500 ml nominal volume fabricated from borosilicate glass 3.3. Bulbous flasks of this type serve as universal laboratory glassware alongside beakers and are routinely employed for distillations as well as for heating liquids. The flat base permits the flask to stand freely without a support ring, while the narrow neck with beaded rim facilitates secure handling and stoppering. A permanently fired white graduation and marking print remains durable under repeated use and cleaning. Laboratory flasks are offered in narrow- or wide-neck versions, with or without ground joints, and as round- or flat-bottom designs; the appropriate configuration is selected according to the intended procedure. This 500 ml model is particularly suited to everyday heating applications. Produced by manufacturer Duran/DWK Life Sciences, the flask combines chemical resistance with thermal stability typical of borosilicate glass 3.3. Supplied as a single piece with a net weight of 0,15 kg, it integrates easily into standard laboratory workflows for preparation, reaction and thermal processing steps.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about DURAN® Flat Bottom Flask, narrow neck, with beaded rim
What is this article?
DURAN® Flat Bottom Flask, narrow neck, with beaded rim is the article on this page. Luminix Health distributes DWK Life Sciences for laboratory use. It sits in Round-bottom flasks, inside Beakers & flasks, in Labware.
A round-bottom flask is the heating flask of a distillation or a reflux. The curved wall takes the heat, and the ground neck connects to a still head or a condenser. The joint size, not only the volume, has to match the rest of the set.
A beaker is an open working vessel: easy to pour, poor as a measure. An Erlenmeyer flask has a flat base and a conical wall so a liquid can be swirled without climbing out. A round-bottom flask is for heating under a condenser, because the heat meets a curved wall and the joint at the neck connects to the rest of the glassware. Borosilicate is the glass that survives the temperature change. These forms are listed under ISO laboratory glassware.
